GATEWAY
PRODUCTS
LifeSize Gateway series consists of the following products:
Gateway-PRI (see About the Gateway-PRI)
Gateway-Serial (see About the Gateway-Serial)
ABOUT THE
GATEWAY-PRI The Gateway-PRI enables audio, video, and data communication between
H.320 endpoints that connect through ISDN, and H.323 endpoints that connect
through a packet-based network. For voice-over-IP, the Gateway-PRI enables
PSTN voice callers to connect from the ISDN network to IP voice callers. The
Gateway-PRI supports two PRI ISDN ports.
ABOUT THE
GATEWAY-SERIAL The Gateway-Serial supports multimedia conferencing over IP by translating
between H.323 and serial protocols. With the help of an Imux, the LifeSize
Gateway can also translate between H.323 and H.320 protocols.
The LifeSize Gateway offers a serial leg for multimedia conferencing over IP by
providing an interface for legacy endpoints with serial interfaces,
encryption/decryption devices, satellite networks and leased line services.

About Gateway Features
ABOUT GATEWAY
FEATURES Table 1-1 lists the major features of the LifeSize Gateway.
Table 1-1 Gateway Feature Summary
Feature Description
Interoperability The LifeSize Gateway provides a high degree of
interoperability with other H.323 compliant gateways,
gatekeepers, terminals, proxy, and Multipoint Control
Unit (MCU) products by being based on the H.320
standard and H.323 protocol stack.
Web-based management The LifeSize Gateway features the LifeSize Gateway
interface. This is a web interface used to configure and
monitor the LifeSize Gateway. You can view and modify
all aspects of the LifeSize Gateway configuration from a
remote location using a Java-enabled web browser.
SNMP management The LifeSize Gateway features Simple Network
Management Protocol (SNMP) management that
supports all aspects of monitoring, diagnostics,
configuration, and trapping.
Diagnostics The LifeSize Gateway features front and rear panel LED
indicators that display status for the unit. You can also
access remote diagnostics of the unit through the
LifeSize Gateway interface, Telnet, SNMP, or a serial
port.
Network load balancing The LifeSize Gateway supports load balancing on the
network by communicating with a gatekeeper through
H.323 RAI (Resource Available Indication)/RAC
(Resource Available Confirmation) messages.
T.120 data collaboration The LifeSize Gateway supports data transfers in calls
between ISDN and IP by using high speed T.120 in
HMLP and VarMLP formats.
Quality of service (QoS) The LifeSize Gateway features configurable coding of
media packets to achieve QoS routing priority on the
Internet Protocol (IP) network. The Type of Service
(ToS) bits of the IP datagram header can be configured
for priority level.

Functionality 3
About Gateway Features
Dial plan The LifeSize Gateway supports a simplified dial plan for
outbound dialing using a single universal prefix. Using
the dial plan, the LifeSize Gateway automatically detects
the capabilities received in the Setup message from the
IP endpoint and sets the same bit rate for the ISDN (or
serial interface) side of the call.
Direct dialing and call routing The LifeSize Gateway dial plan supports the following
direct dialing and call routing facilities:
Direct Inward Dialing (DID)
Multiple Subscriber Network (MSN)
Q.931 Sub-addressing Information
Element
Gateway-Serial supports DID in DCE mode
only.
Internal and External Interactive Voice
Response (IVR)
TCS4
Default extension
Access control The LifeSize Gateway features password-controlled
access to the LifeSize Gateway interface. Up to ten
different administrator access profiles can be defined for
the LifeSize Gateway.
DTMF translation The LifeSize Gateway supports translation between
in-band Dual Tone Multi-Frequency (DTMF) signals (on
the ISDN side) and out-of-band H.245 messages (on the
IP side). DTMF translation occurs for voice and video
calls.
Dual video The LifeSize Gateway supports H.239 standards-based
dual video and TANDBERG DuoVideo technology. Dual
video streams enable a screen to carry video images from
one source while simultaneously displaying images from
a second source.
Table 1-1 Gateway Feature Summary (continued)
Feature Description

4 LifeSize Gateway Installation Guide
About Gateway Features
Conceal caller ID The LifeSize Gateway supports a conceal caller ID
feature that instructs the gatekeeper to conceal the
identity of the calling endpoint on the IP or ISDN
network, whether the presentation restricted feature is
enabled or not.
H.323 fast start The LifeSize Gateway H.323 fast start feature enables
endpoints to join a voice conference in the LifeSize
Gateway more quickly.
ISDN rollover (available in
Gateway-PRI only) The LifeSize Gateway features ISDN rollover. In this feature, the LifeSize Gateway sends a “busy out” channel
request to the PSTN switch when the current PRI
connection is left with less than a predefined number of
available B channels. The PSTN switch “rolls over” to
the next available gateway.
Network Specific Facility
(available in Gateway-PRI
only)
The LifeSize Gateway provides support for Network
Specific Facility Information Elements (NSF IEs) which
enable system administrators to specify to service
providers the equipment, service, or network through
which they want a call routed.
ISDN connection failure The LifeSize Gateway responds to ISDN connection
failure events, by unregistering from its gatekeeper. The
gatekeeper is forced to send new IP-to-ISDN calls
through a different gateway, thus ensuring high call
completion rates. The LifeSize Gateway re-registers to
the gatekeeper when the ISDN connection is restored.
Downspeeding The LifeSize Gateway features downspeeding
functionality. In the downspeeding feature, the LifeSize
Gateway attempts to reconnect a disconnected video call
either at a lower bandwidth or as a voice call.
Downspeeding contributes to a higher percentage of call
completion on the network. The LifeSize Gateway
supports downspeeding at call setup and in mid-call.
Multiple trap server support The LifeSize Gateway supports up to three SNMP trap
servers.
Table 1-1 Gateway Feature Summary (continued)

About Gateway Features
Table 1-2 lists features for specific LifeSize Gateways.
H.239 support The LifeSize Gateway supports the H.239 protocol in
ISDN-to-IP calls and in IP-to-ISDN calls.
Encryption support The LifeSize Gateway supports H.235-compliant AES
128 encryption for calls over IP networks, and H.233 and
H.234-compliant AES 128 encryption for calls over
ISDN networks.
H.243 Conference Control
support The LifeSize Gateway supports the H.243 protocol in ISDN-to-IP calls and in IP-to-ISDN calls. The LifeSize
Gateway identifies the protocol version that an IP
endpoint uses and sends H.239 capabilities only to those
endpoints working with protocol version 4.0 or later.
Peer-to-peer connectivity The LifeSize Gateway supports connectivity to the IP
network through a gatekeeper, or directly to a peer
device.
IP network connections The LifeSize Gateway has one 10/100Base-T Ethernet IP
port (on the front panel) and connects to an IP segment
through a direct connection to a network switch.

CONFERENCING The LifeSize Gateway-PRI enables H.323 endpoints on the IP network to
communicate with an H.320 terminal, an ISDN phone, or a regular phone on a
circuit-switched public network without having to connect directly to these
networks. The LifeSize Gateway allows all IP network terminals to support
video conferences without connecting every desktop computer to an ISDN line
(see Figure 1-1).

CONFERENCING
The LifeSize Gateway-PRI enables direct video, voice, and data communication
between an H.320 (ISDN) terminal and H.323 (IP) terminals at bandwidths of
up to 1472 Kbps (23B bonding for T1) and up to 1920 Kbps (30B bonding for
E1) (see Figure 1-2).

ABOUT MULTIPOINT
CONFERENCING Together with the LifeSize Multipoint, the LifeSize Gateway-PRI enables H.320
ISDN terminals to participate in a mixed ISDN-IP multipoint multimedia
conference with IP network endpoints (see Figure 1-3).
For example, when an H.320 ISDN terminal wants to participate in a multipoint
conference with H.323 IP endpoints, the H.320 ISDN terminal can either join
the multipoint conference by dialing to the LifeSize Gateway, or be invited into
the conference by one of the participating IP endpoints. In either case, the
LifeSize Gateway connects the ISDN terminal to the LifeSize Multipoint,
enabling it to participate in the multipoint conference.
